Abstract: This paper presents a System on Chip(SoC) used for non-magnetic flux meter, which can be used to detect various types of rotations. The focuses of the design are the architecture of SoC, the non-magnetic digital algorithm module and the connection between the microprocessor and external devices. By applying unified addressing techniques in the system, the microprocessor can directly control external devices. The chip is fabricated using standard 0.35 μm CMOS technology. Test result shows that the digital module of the SoC chip works properly.

Key words: System on Chip(SoC), architecture design, unified addressing, I2C protocol, non-magnetic algorithm
